Hi, Whether investing in one of the fastest or two medium-high end GPU depends on your workload: system size, type of run, single or multiple simulations, etc. If you have multiple simulations you can run independently or coupled only weakly in ensemble runs (e.g. using -multidir), multiple mid-ti

Hi, A CPU:GPU ratio of 4:1 is fairly well balanced these days (depending on the quality of the hardware), so you should expect to roughly double your throughput adding a second GPU to your current system. However, that doesn't mean your single simulation performance will double - it's a lot more e

Hello, Previously, I have helped building a workstation for my fellow researcher who heavily uses GROMACS for his MD simulations, with the following base specs: -CPU: 8 cores (Xeon E2278G) -RAM: 32GB -GPU: 1x RTX2080Ti With this setup, he managed to shrink down each simulation runtime to, say a
